For  a  quarter  of  a  century  the  above  word  has  been  our 
registered  trade  mark,  a  protection  to  our  customers,  and 
a  guarantee  of  quality  and  satisfaction. 

The  word  Jux£ejr  is  derived  from  the  Latin  word  LUX 
meaning  light,  and  FERRE  to  carry. 

It  is  used  by  the  American  Luxfer  Prism  Co.  to  desig¬ 
nate  their  patented,  daylight  projecting  prisms. 

This  company  is  the  largest  manufacturer  of  prism 
products  for  the  distribution  of  daylight,  in  the  world. 

It  was  the  first  to  perfect,  patent  and  market  these 
products. 

We  make  this  statement  merely  to  acquaint  you  with 
our  position  in  the  trade  and  to  indicate  why  we  feel 
certain  of  our  ability  to  serve  you. 

Our  sole  business  is  to  extend  the  lyxfer  Daylighting 
System,  through  the  use  of  the  different  forms  or  types 
of  ]_ux£er  Prisms,  in  sidewalks,  show  windows,  sky¬ 
lights,  windows,  floors  and  ceilings. 

Our  facilities  for  the  prompt  completion  of  contracts  and 
the  shipment  of  orders,  are  as  near  perfect  as  can  be. 

We  have  sales  offices  in  the  principal  cities  of  the 
United  States,  and  large  manufacturing  and  glazing 
plants  in  Chicago  and  New  York.

You  are  a  retailer,  engaged  in  the  business  of  selling  to  the  multitude  merchandise 
and  wares  in  which  there  is  competition  and  which  may  be  purchased  around  the 
corner  from  a  trade  rival,  you  will  know  that  there  are  certain  fixed  elements 
which  make  for  the  success  or  failure  of  the  store. 


Of  all  the  factors  contributing  to  success,  however,  none  is  greater  or  more 
potent  than  DAYLIGHT. 


Not  only  is  a  store  flooded  with  daylight  conducive  to  cheerfulness  and  de¬ 
structive  of  doubt  and  criticism,  but  it  is  cheaper  in  maintenance. 

The  store  in  which  there  are  dim  corners  and  dark  aisles  suggests  dirt  and 
uncleanliness  or  something  defective  concealed  that  would  suffer  if  exposed  to 
the  light  of  day. 

An  attractive  store  front  is  an  eloquent  advertisement  of  a  store’s  business.  If, 
however,  the  first  pleasant  impression  created  by  the  window  is  not  maintained 
after  the  prospective  customer  has  crossed  the  threshold,  but  on  the  contrary  is 
dispelled  by  a  drab  and  sickly  light  in  which  merchandise  may  be  examined  only 
imperfectly,  the  appeal  created  by  the  window  v/ill  be  lost. 

Where  the  store  handles  materials  in  which  the  element  of  color  enters,  this  lack 
of  daylight  will  not  be  made  up  by  artificial  lighting,  no  matter  how  prodigally 
used,  for  the  simple  reason  that  colors  and  shades  assume,  under  artificial  light, 
a  tinge  they  do  not  have  under  natural  light. 


The  public  are  more  and  more  giving  preference  to  the  daylight  store. 
Daylight  inspires  confidence. 


It  should  therefore  be  apparent  to  merchants  and  store-keepers  that  every  day 
lost  in  converting  their  stores  into  daylight  stores  brings  with  it  a  double  finan¬ 
cial  loss — the  cost  of  gas  and  electricity  consumed  and  the  loss  of  trade. 


If  you  can’t  match  Dress  Goods 
and  Silks  in  any  aisle  in  your 
store  you  need  Jux-fer  Prisms. 


Are  you  paying 
big  bills  for  Gas 
and  Electric 
Light  con- 
sumed  during 
daylight  hours? 

Put  in  ]uxfer- 
Prisms  and 
save  the  ex¬ 
pense.

Prisms  are  a  scientific  product,  created  for  the 
purpose  of  bringing  daylight  into  dark  interiors,  and  accom¬ 
plish  that  purpose  thoroughly  and  efficiently. 

]uxfer  Prisms  are  sections  of  crystal  glass  of  a  standard 
dimension  of  four  inches  square,  having  a  smooth  outer  sur¬ 
face  and  an  inner  surface  divided  into  a  numerous  series  of 
small  accurately  formed  prisms. 

This  size  has  been  found  by  experience  to  be  the  best,  as 
the  prisms  can  be  pressed  to  a  true  and  perfect  angle,  an 
absolute  necessity  for  scientific  accuracy,  and  is  artistically 
best  suited  for  the  type  of  store  fronts  and  windows  that  prevail 

in  modern  buildings.

LUXFER  STANDARD  METHOD  OF  GLAZING. 

Luxfer  4"  Pressed  Prism  Tiles  are  made  up  in  panels  of  any  size  required,  to  fit  the  open¬ 
ings  in  which  they  are  to  be  installed. 

The  proper  angle  prism  to  meet  the  daylighting  requirements  at  the  building  where  they 
are  to  be  installed,  is  prescribed  by  our  engineers. 

The  Prism  Tiles  are  glazed  in  hard  metal,  drawn  bar  and  each  panel  is  finished  with  a  flat 
metal  margin  or  bar,  the  thickness  of  ordinary  plate  glass,  and  of  the  required  width  to  fit 
the  rabbet. 

The  bars  and  margin  are  securely  soldered  at  all  intersections,  on  both  sides  of  panel,  then 
stiffened  to  withstand  wind  strain  by  soldering  on  the  inside  of  panels,  at  frequent  inter¬ 
vals,  flat  galvanized  steel  bars,  set  on  edge.  These  stiffening  bars  are  one-eighth  of  an  inch 
in  thickness  and  vary  from  a  half  to  three-quarters  of  an  inch  in  width,  according  to  the 
height  of  panel. 

The  whole  panel,  all  soldering  done,  is  then  given  a  heavy  coat  of  copper,  which  covers  the 
otherwise  unsightly  solder  joints  as  well  as  the  steel  stiffeners  and  adds  materially  to  the 
strength,  rigidity  and  beauty  of  the  panel. 

The  panel  is  then  cemented  and  made  thoroughly  water  and  weather  tight,  and  the  metal 
polished. 

The  panels  are  set  in  exactly  the  same  manner  as  plate  glass  and  in  the  same  arrangement 
of  sash  and  frames,  the  necessity  for  skilled  labor  being  eliminated  entirely. 


A  short  specification 
that  will  protect  both 
you  and  your  client:

front  transoms,  and

IT  IS  IMPORTANT  that  the  correct 
angle  of  prism  be  used.  Our  engineer¬ 
ing  department  attends  to  that  for  you. 
Every  installation  requires  specific 
treatment. 

The  above  cut,  for  instance,  shows  the 
difference  in  angle  of  prisms  required 
on  a  60-ft.  street  and  a  100-ft.  street, 
both  having  a  4-story  building  opposite. 
NOTE:  The  path  of  light  must  be 
diffused  horizontally,  for  both.

Cleaning  Luxfer  Prisms 

All  that  is  required  to  maintain  the  light-giving  power 
of  \ux-feir  Prisms  for  all  time  is  to  keep  them  clean. 

Give  them  the  same  care  and  attention  that  you  give 
the  plate  glass  in  your  show  windows.  When  you  clean 
the  plate  glass,  clean  the  prisms  at  the  same  time  and  in 
the  same  manner. 

The  outside  of  the  prism  is  as  smooth  as  plate  glass. 

The  prisms  on  the  inside  should  be  scrubbed  once  a 
month  with  an  ordinary  scrub  brush  and  a  solution  con¬ 
sisting  of  a  teacupful  of  ammonia  added  to  a  pailful  of  hot 
water. 

Tux^er'  Prisms  when  cared  for  in  this  manner  will 
remain  as  bright  as  when  installed  —  indefinitely —  1 00% 
efficient.
